These are general guidelines measured from our own
flight tests. You can experiment with higher rates to
match your preferred style of flying.
Travel Adjust, Sub Trim and Dual Rates are
not listed and should be adjusted according
to each individual model and preference.
Center of Gravity
An important part of preparing the aircraft for flight is
properly balancing the model.
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location
for the BAe Hawk is 3

/
8
to 3

/

-inch (80 to 90mm)
back from the leading edge of the wing. Mark the
location for the Center of Gravity on the top of the
wing next to the fuselage as shown.
When balancing your BAe Hawk, support the plane
inverted at the marks made on the top of the wing with
your fingers or a commercially available balancing
stand. Adjust components as necessary so the model
hangs level or slightly nose down. This is the correct
balance point for your model. You might find you may
be required to add a small amount of weight to either
the front or back of the fuselage to achieve the correct
balance.
After the first flights, the CG position can be adjusted
for your personal preference.
Preflight
Check Your Radio
Before going to the field, be sure that your batteries
are fully charged per the instructions included with
your radio. Charge both the transmitter and receiver
pack for your airplane. Use the recommended charger
supplied with your particular radio system, following
the instructions provided with the radio. In most cases,
the radio should be charged the night before going
out flying.
Before each flying session, be sure to range check your
radio. See your radio manual for the recommended
range and instructions for your radio system. Each
radio manufacturer specifies different procedures for
their radio systems. Next, start the motor. With the
model securely anchored, check the range again.
The range test should not be significantly affected. If
it is, don’t attempt to fly! Have your radio equipment
checked out by the manufacturer.
Note: Keep loose items that can get entangled
in the propeller away from the prop. These
include loose clothing, or other objects such as
pencils and screwdrivers. Especially keep your
hands away from the propeller.
Double-check that all controls (aileron, elevator, rudder
and throttle) move in the correct direction.
Check the radio installation and make sure all the
control surfaces are moving correctly (i.e. the correct
direction and with the recommended throws). Test run
the motor and make sure it transitions smoothly from
off to full throttle and back. Also ensure the engine is
installed according to the manufacturer’s instructions,
and it will operate consistently.
Check all the control horns, servo horns, and
clevises to make sure they are secure and in good
condition. Replace any items that would be considered
questionable. Failure of any of these components in
flight would mean the loss of your aircraft.
